Not if you fight a war for it or pay them for it. So no, stop trying to spread that white guilt around. The Natives lost, so did the Mexicans, who also "stole" the natives land as well as the Canadians. People always attack America but always forget Canada and Mexico are the French and Spanish(Spain) versions of the US.
So no, not their land anymore. It's our(including them as they are Americans too) land Notice it;s always guilty white people who try and placate to the natives? The natives don't hate us, you white guilters do. :l
